On this page you can find links to various SDR receivers around the world.http://websdr.org/
Although they don't allow yet DRM reception it is interesting to see how strong the signals are.
Some wide band receivers are using simple RTL dongles and up converters.

Here is a picture showing signals from BBC and RFI in USA this morning

Thanks for the link
I have tried the global tuner solution but I am not impressed.
Single user
Too much latency
No spectrum display
It could be useful for broadcast FM reception but you need to know what you are looking for.

It works. I listened just now to BBC on 17.790 MHz in DRM, but the reception is better here in Stockholm. An advantage is that you can listen to the frequency in AM and, if you hear that there is a DRM signal on the channel, then you just press DRM. You get decoded audio, but nothing else.
